PATENT OFFICE PENNSYLVANIA, ASSIGNORS '10 VENDI CATER,'INC., OFWILLIAHSPORT, PENNSYL- VANIA, A CORPORATION OF PENNSYLVANIA VENDINGMACHINE Application filed August 27, 1929,1SeriaLNo. 888,651. RenewedJune 23, 1931.

This invention relates to vending machines and pertains more especiallyto a machine I for vending bottled liquids and has for an object new andimproved coin controlled means for controlling the operation of themachine.

In our co-pending application, Ser. No. 340,462, filed February 16,1929, there is disclosed a machine consisting of a casing within whichis rotatably mounted a frame equipped with a plurality of compartmentsin which are arranged the bottled goods to be sold. Thecasing'isiprovided with a door 'which when opened permits access to acompartment. Means controlled by the door are.

provided for advancing the frame to the extent of a single compartmentupon each opening and closing of the door, these means being so designedthat substantial movement of the frame is prevented until the door isvirtually closed.

An object of this invention is a new and improved coin releasablelocking device for the 'door of such character that the door when closedsufficiently to permit rotation of the frame is locked againstre-opening, thereby v preventing the obtaining of access to more thanone compartment by the use of a single coin. 1

Other objects, novel features and advantages of this invention will beapparent from the following description and accompanying drawings,wherein I Fig. 1 is a vertical section through a ma chine embodying theinvention. 7

Fig. 7 is a section on the line 7 7 of Fig. 3.

'Figs. 8, 9 and 10 are sections taken on the line 8"-8 of Fig. 7 showingdiflerentpositions assumed by the various parts, and

Fig. 11 is a fragmentary section on the line 11-11 of Fig. 8.

The machine comprises a cylindrical casing 10 which islf divided into anupper and a lower chamber by a partition 11 the upper chamber beinprovided with a removable cover 10a. In the lower chamber there isprovided a shelf 11a and a vertical hollow shaft 12 is suitablyjournalled in the shelf and partition and projects slightly into theupper chamber. At its upper end this shaft 12'ca-rries a circular plate13 by which is sup ported an annular frame 14 which is made up of aplurality ofsuperposed shelves 15 divided into compartments 15b byradial partitions 15a. Clips 150 may be provided in the compartments tohold the bottles. Within the frame 14 and supported by the plate 13 isprovided a tan}; 16 to receive ice or within which may be provided anysuitable refrigerating apparatus, the tank 16 having an outlet 17leading to the hollow shaft 12. The shaft 12 is provided with a drum 18around which is wound a cable 19 which passes over a pulley 20 and isattached to a weight 21. The weight 21 and cable 19 are effective tocause rotation of the plate 13 when released, the plate normally beingheld against rotation by means subsequently to be described. A lining16a of heat insulating material is provided for the upper chamber.

An elongated aperture 'ofsubstantially the same height as the frame 14is provided in v the wall of the upper chamber and a casing 105 ismounted in said aperture. and has a portion 100 overlying the wall ofthe casing laterally of the aperture. A door 22 is hinged .to the casingand is provided with an extension 23 (Fig. 4) projecting into the casing10. Preferably the door 22 is provided with a glass panel 22a throughwhich one vertical row of compartments 15b is visible. The plate 13 isprovided on its peripherv with uniformly spaced shoulders 24 which areadapted to be engaged by a pawl 25 pivotally supported by the partition11 and having an arm 25aengagingthe extension 23 of the door 22. Aspring 26 tends to maintain the pawl 25 in position to engage.

a shoulder 24 to prevent rotation of the plate 13 under the influence ofthe weight 21. A

7 hinged cover 31, which is locked in closed detent 27 is pivotallymounted on the partition 11 and is provided with a socket for thepurpose of receiving one of the uniformly spaced pins 28 extending fromthe lower face of the plate 13. A spring 29 maintains the detent 27inengagement with the extension 23 of thedoor 22. The shape of the extension 23 is such that when the door 22 is opened the pawl 25 is moved outof engagement with the shoulder. 24 and the detent 27 is moved inwardlyto receive a pin 28 in its socket, the pin 28 being received in thesocket before the pawl 25 is disengaged from the shoulder 24. The socketin the detent 27 is slightly wider than the pin 28, thereby allowingslight movement of the plate 13 after the pawl 25 is disengaged'from theshoulder to prevent re-engagement of the pawl with the pin from which itwas just disengaged. The arrangement above described constitutesescapement mechanism mechanism is so designed that it becomes operativebefore the door 22 is closed suificiently to render the detent 27inoperative, thereby making it impossible to obtain access to acompartment after the frame has been advanced a step, except byinserting another coin in the coin controlled mechanism. The door 22 isequipped with a closing spring 226.

The door 22 is provided with an extension 30, (Figs. 2 and 3) whichoverlies the part 100 of the casing 10b, the extension 30 being recessedto form a chamber 30a closed bya Y position by the bolt 31a. The bolt isoperable by a key inserted in the tumbler cylinder 316 when the door 22is open. A hasp 32 is carried by the part 100 of the casing 106 andprojects through a slot in the cover 31 i into the chamber 30a. Avertical guide 34 (Figs. 7 to 11) is supported by the front wall of thecom artment 30a and within the guide is mounte a slide 35 having alongitudinal bore. A locking bolt 36 having an oblique surface 36a isslidably" mounted in the bore of the slide 35. A vertical guide38 issupported by the guide 34 and in it is slidably mounted a second lockingbolt 39 having an oblique surface 39a. A pin 37 passes through thelocking bolt and slots 35a in the slide and extends through a slot 34ain the guide 34 and also through a slot 38a in the guide 38 into asocket in the locking bolt39, thus fastening the two bolts together forunitary movement. The two locking bolts are so arranged that bothproject within the hasp 32 when the door 22 is closed, the upper end ofthe bolt 36 being in engage- .ment with the cross member of the hasp. A

spring 40 exerts upward pressure on the locking bolt 39. A pin 42 iscarried by the slide 35 and extends across the bore of the slide andalso projects through a slot 346 in the guide 34. In the lower end ofthe bore of the slide 35 there is slidably mounted a plug 43 and to thepin 42 and the plug 43 are fastened the ends of a spring 44 while to thepin 42 and the bolt 36 are fastened the ends of aspring 45. The lowerend of the bore is inwardly flanged to prevent escape of the plug 43 andthe lower end of the slide 35 is cut out at 350 for a purpose which willlater become apparent. The relationship of the pin 42, locking bolt36,plug 43 and the springs 44 and 45 is such that when the locking bolt 36is in its upper or operative position, the plug 43 is held in the boreabove the cut-out 350 (Fig. 8). A pin or stud 46 is carried by the part100 and projects, when the door 22 is closed, through an aperture in thecover 31, an aperture in the guide 34, below the cut-out 35c and underthe cup 43. The projecting end of the pin 42 is engageable by shoulders47 and 47a formed on a rotatable member 48 which is normally held by aspring 49 with the shoulder 47 engaging the pin 42 as shown in Fig. 7.The rotatable member 48 is operable by a handle 50 through the medium ofa coin inserted into the recess 50a, the coin being effective to permitoperation of the handle 50 in a. manner common to a well-known type ofcoin release locks. 4 I

Access is normally prevented to alI but the upper shelf of the frame 14by shields 51 which are slidably mounted in guides 52a projectinginwardly from the wall of the casing 10, Each shield is provided with anaperture 53 which, in one positionof the shields, registers with thedoor 22. Springs 55 are provided tending to draw the shields intoposition'to register the apertures with the door 22 but the shields arenormally held out gof such position by means" of spring latches 54mounted on the casing wall and provided with shoulders which engage theedges of the apertures. As described in the co-pending application ofMcCormick, et al. Ser. No. 340,462, filed February 16, 1929, means areprovided to release the shields as the compartments of theshelvesebecor'ne exhausted.

The operation of the device as described up to this point is as follows:Assume that the compartments of the various shelves have been filledwith bottles and that the compartments equipped with the flaps. 56 arein register with the door 22. The shields 51' are held in retractedposition by the latches 54 so that only the top compartmentwill beaccessible when the door is opened. The weight and 39 are the positionshown in Fig. 8. Assume now that a coin is inserted through theslot 50aand the handle 50 is turned to bring the shoulder 47a intoengagenientwith the pin 42. By virtue-of such engagement, the slide 35 is pulleddownwardly and asthe upper end of the slot 35a .in the slide engages thepin 41, the bolts 36 and 39 are drawn down out of the way of the hasp sothat the door may be opened (Fig. 9) Opening of the door removes thepawl from ths shoulder 24 and brings the detent 27 into operativeposition, thereby permitting slight rotation of the table '13 (Fig. 5).The bottle may now be removed from the registering compartment afterwhich the door is closed, either manually or by its spring, the lockingbolts being moved downwardly by engagement of their oblique surfaceswith the 'crossmember of its hasp 32, thereby rendering the detent 29inoperative and permitting the plate 13 to advance until the pawl 25engages the next shoulder 24, thereby bringing a new compartment intoregister with the door 22. v

The plate 13 is released by the detent 27 just before the door 22 iscompletelyclosed and means are provided for preventing advantage beingtaken of this fact to obtain more than one bottle with a single coin.-When the pin 42 is moved downwardly the H spring 44 is compressed andpresses the plug "43 against the pin 46-(Fig. 9). As the door is openedthe plug 43- moves out of contact with the stud 46 and is then presseddownward into theposition shown in Fig. 10, its downwardmovement beinglimited by the flanges at the bottom of the slide 35. The

plug 43 will remain in this position until the.

pin 42 is returned to normal position by the shoulder 47, and in thisposition it is im possible to close the door sufiiciently to release thedetent 27 since the stud 46 will engage the plug 43. In order for thedoor to close, under such circumstances, sufiiciently to disengage thedetent 27 it is necessary first to release the handle so that the member48 may be returned to the position shown in Fig. 8 by the spring 49whereupon the pin- 42 will be returned by the shoulder 47 to theposition shown in Fig. 8 and the plug 43 will bei returned to theposition shown in the gure.

The bolts 35 and 39 are thereupon projected by their springs intolocking. position and turning of the handle 50 is prevented since thecoin was dropped from the slot 50d when the handle 50 reached the limitof its rotatlon. Closure of the door suflicicntly to render the'detent27 inoperative, places the bolt 39 in engagement with the hasp 32 andprevents and having a refund for such bottles. An

aperture is provided in the wall of the lower chamber and a cylindricaltray is-supported therein. The cover 61 is arranged at the upper part ofthe aperture and the ends of a shaft 62' are journaled in the tray andcover. A collar 63 is keyed to the shaft 62 and is provided with ahandle 64 which projccts through a slot in the lateral wall of the tray60. A carrier 65 is also keyed to the shaft and rests upon the collar63. A helical spring 66 has one end attached to the tray 60 and theother end of the lever 64 normally tends to hold. the bottle carrier inposition to receive the bottle. By means of this mechanism a bottle ispresentedto the refunding mechanism (not shown) and is discharged ontothe shelf 84 having a sloping portion which overlies a receptacle 85having a sloping bottom 86. The remaining mechanism of the bottlerefunding mechanism and the operation thereof is fully described in thecopending application of McCormick, et al. Ser. No. 340,462, filed Feb.16, 1929.

The coin used to release the locking mechanism is dropped into a chute90 in which it is held in back of a magnifying glass 91 until themachine is again operated (Fig. 7 The coins with which the machine hasbeen operated are thus temporarily displayed and make it possible for anobserver easily to discover whether a slug has been used instead of acoin. A pivoted arm 93 extends into the chute 90 and acts as a stop tolocate the coin in front of the glass. This arm is pressed toward a stoppin 93a by a spring 935. A pivotally mounted lever 94 is provided with alip 94a which engages'a lip 930 provided on the arm 93. A spring 95tends to hold the lever 94 in the position shown in Fig. 8, while a stud96 is provided on the rotating member 48 to engage the upper end of thelever 94. The operation of this mechanism is as follows: The coin'cwhich was last used to release the locking mechanism is supportedin thechute in front of the magnifying glass by the arm 93'. As the member 48is rotated, the stud 96 engages the upper end of the lever 94 and movesthe same slightly. By reason of the engagement of the lips 930 and 94athe arm 93 is moved against the action of the spring 936 sufficient topermit the coin 0 to drop. The stud 96 moves out of engagement with theupper end of the lever 94 allowing it to be returned to'normalposition.by the spring 95 which permits the spring 936 to return the arm 93 intoposition to be engaged by the coin by means of which the lock has justbeen released. As the rotating member48 is.returned to normal position,the stud 96 again 7 trips the lever 94, but this has no efl'ect on thearm 93 as the lips 930 and 94a merely move away from each other and thenback into contact. 7

It is oi pourse understood that various structural modifications may bemade in the device above described, without in any Way departing fromthe spirit of the invention as ient member.
